  <div> 
	 <p>There are some applications that best express dependencies as messages
		passed between nodes in a flow graph. These messages may contain data or simply
		act as signals that a predecessor has completed. The <span class="keyword">graph</span> class and its
		associated node classes can be used to express such applications. All
		graph-related classes and functions are in the <span class="keyword">tbb::flow</span> namespace.
